This may not help, but at least it breaks the silence. :)

I've not used DRBD in a VM, but I do use it between dom0s via a real 
switch and I use bridging between a set of VMs. As I've gotten my system 
set up, my bridges don't have IPs themselves. In this configuration, 
they are essentially just switches... Not addressable devices.

So what I am wondering is; Could your problem be a mis-configuration on 
the networking instead of an actual problem with DRBD? To be honest, and 
I am no expert, I don't see how the difference between real and virtual 
switches/bridges should affect DRBD at all.
